AUTOMATIC CAR-BRAKE.

:alrECIFlCAlJEQIQ' forming part of Letters Patent No. 698,319, datedApril 22, 1902/ Application filed m 11, 1901. Serial No. 67,899. (Nomodel.)

To all whom, it may concern."

I Beitknown thatI, ARTHUR W.,REED,3, cit-i-' zen of the United States,residing at Orvisburg, in the county of Pearl River and State ofMississippi, have invented a new and use-, ful Automatic Car-Brake, ofwhich the followa ing is a specification.

The invention relates to improvements in automatic car-brakes.

The object of the present invention is to improve the construction ofautomatic carbrakes and to provide a simple, inexpensive, and eificientdevice designed for use. onvarious kinds of cars, especiallylogging-cars, and adapted to be readily applied to the same and capableof enabling the brakes to be controlled and applied by the'engineen.

The invention consists in the construction and novel combination andarrangement of partshereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

sponding In the drawings, Figure lis a plan view of a portion of a carprovided-with a device constructed in accordance with this invention.Fig. 2 1s a similar view, the transverse lever being disconnected fromthe coupling-pole and the chain being attached to thesame to arrange theparts for backing.

Like numerals of reference designate correings.

1 designates a portion of the frame ofa log ging -car havinglongitudinal draft-timbers 2,

connected by upper and lower transversebars 3 and 4 and receiving theshank 5 of a draw-head 6, whiohis designed to be'counect-' dinal bar 17.

parts in all the figures of the draw eration of the car-brakes by'theconstruction hereinafterdescribed. The car-coupling may be mounted inany. other suitable-manner to secure the-necessary longitudinalmovement. 7

. Fulcrumed on one side of the frame of the car is atransversely-disposed'lever 11', which is connected at its outer endwitha longitudinal rod 12, designed to extend to and .be connected with theordinary car-brake, (not shown,) whereby when the rodis moved out wardlongitudinally an application of the brakes will be effected. The outerend of the rodis connected with the outer arm of the transverse lever 11by a-shortchain 13, and

the lever is provided with a series of perforations 14, adapted toreceivea bolt or other suitable fastening devi'cefor connecting the I'11 is provided with a central aperture for the reception of a pivot 15,and itsinner arm is provided at its outer portiouwith a fork orbifurcation 1G for the reception of a longitu- The longitudinal bar 17extends forward from the transverse lever and is pivoted detachably by apin 18 to a bracket or bar 19 of the coupling-pole 8. The rear portionof the longitudinal bar 17 is provided with a series of perforations 20to receive the 'pivot 21 for connecting the said bar 17 to the inner endof the transverse lever. The bracket or bar, which is suitablysecured tothecou'p ling-pole, hasits rear portion offsetfrom the "same, and thefront'end of the bar17 is bifurcated or forked to receive the saidbracket or bar 19. The cushioning-spring of the car is designed to be ofsufficient strength to permit the car to be backed on a level or slightincline without compressing the spring or applying the brake; but whenthe cars are in motion the engineer, by reducing the speed of thelocomotive, may create sufficient pressure to compress the spring andproduce an application of the brakes. In this manner the brakes will beautomatically applied, and a train will be completely under the controlof the engineer.

When it is desired to arrange the parts for backing a train of ears, thetransverse lever is disconnected from the coupling-pole by de tachingthe front end'of the bar 17, and .the rod 12 is connected with thecoupling-pole by a chain 21. The chain 21, which is connected at itsrear end to the outer arm of the lever 11 and which may form acontinuation of the chain 13, is provided at its front end with a hook22, adapted to engage an eye 23 of the coupling-pole, as clearlyillustrated in Fig. 2 of the accompanying drawings. The eye 23 ispreferably formed by an eyebolt, which passes through the coupling pole.Should the engine While backing a train in this manner reduce its speed,the chain will be drawn taut and the rod drawn outward and the brakesapplied. When the inner end of the transverse lever 11 is connected withthe coupling-pole, as illustrated in Fig. l of the drawings, the chain21 is disconnected from the coupling-pole and hangs down from the outerarm of the lever 11, as illustrated in Fig. 4.

I It Will be seen that the attachment is exceedingly simple andinexpensive in construction, that it is adapted to be readily applied toa car, and that it is capable of enabling the brakes to be controlled bythe engineer. It will also be apparent that the attachment is applicableto various kinds of cars and that the attachmentmay be readily arrangedeither for backing or hauling a train.

The device is adapted for use on cars not employing coupling-poles, andthe bracket or bar 19 or analogous member will be mounted on a car,motor, or other vehicle for the reception of the detachableconnecting-bar 17, and the chain 21 will then be connected to such car.

What is claimed is-- 1. In a device of the class described, thecombination with a car having a car-coupling capable of longitudinalmovement, of a transverse leverfulcrumed on the car and designed to beconnected at one end with the brakeoperating connections, and means forconnecting either the inner or outer arm of the lever with the draftmechanism, whereby the parts are arranged either for backing or haulinga car or train, substantially as described.

2. In a device of the class described, the combination with a carprovided with a carcoupling capable of longitudinal movement, ofatransverse lever fulcrumed between its ends on the car, means forconnecting the outer end of the lever with a car-brake, a coupling-poleconnected to the car-coupling, the longitudinal bar connected to theinner arm of the transverse lever and detachably secured to thecoupling-pole, and a chain connected with the outer arm of the lever andprovided with means for detachably engaging the coupling-pole,substantially as described.

3. In a device of the class described, the combination with a car havinga car-coupling capable of longitudinal movement, of a brakerod, aflexible connection extending from the outer end of the brake-rod, atransverse lever fulcrumed between its ends and secured to the saidflexible connection, a coupling-pole connected to the car-coupling andprovided with a bracket or bar, a bar pivoted to the inner end of thelever and detachably secured to the bracket or bar of the coupling-pole,and means for detachably connecting the outer end of the lever with thecoupling-pole, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
